Frequently asked questions

What is the difference between the Fluidmaster 400A and 400LS?

Both are toilet fill valves. The 400LS adds Leak Sentry, which is designed to stop the refill when the flapper leaks.

Which Fluidmaster flapper fits my toilet?

Measure the flush valve opening in the bottom of the tank. Most toilets use a 2" or 3" valve; the PRO58 is a 3" adjustable flapper, and the PRO53, PRO54 and PRO55 are universal-fit flappers.

What toilet supply line do I need?

Most toilets take a 3/8" compression x 7/8" ballcock supply. Measure from the shutoff valve to the fill valve shank and choose the next length up.
